wnArPrin-APPLYING ivrncnnmsia.

To all whom it may concern Be it known that I, JAMES B. HARRIss, a

. citizen oi the United States, residing at Newark, iii the county of Essex and State ot New Jersey, have invented new and useful Improvements in Wrapper-Applying Mechanisms, of which the following is a speciu fication.

Thisinvention relates to improvements in wrapper vapplying mechanisms, ypertaining more particularly tothe application of a loose wrapper about a packet to produce a wrapped package.

The present particularly for the wrapping of .packages of regular contour, preferably having faces extending angularly to each other, such for instance as closed boxes or cartons, plug tobacco, etc., the mechanism being or'. a type to permit of relatively high capacity, the wrapping operation being completed during travel of the packet continuouslyA in an approximately horizontal plane, adhesive being applied durin the advancing movement, thereby comp eting the wrapped package during such movements.

Other objects .are nism which is simple and eiiicient in operation, durable in construction, and which will operate in connection with various forms ot wrapping material.

To these and other ends, the nature of which will be readily understood as the in' said inven- Y vvention is hereinafter disclosed, tion consists in the improved construction and combination of parts hereinafter more fully described, illustrated inA the accompanying drawings, pointed out in the appended claims.

As shown in Fig. 2, the` width 4ofrcess 4()a is less than the length of the charge, so that the under face of the lower charge, when in the ma azine, rests upon the top face`of table 40. hen, therefore, a member 46a'pas'ses` into contact with the rear vancing movement of member 46a carries the charge out of the magazine and advances it along, the table ftop which' is substantially on a single plane throughout its len h. v

haft 44 is preferably mounted in an adjustable bearing 48 by means of which the chains can be held at the desired tension.

The movements of the carrier are provided from a shaft 49 extending longitudinally of the machine below the table, shaft 49 being driven from a suitable drive shaft 50, the latter having a worm 50a which engages a worm gear 51 on shaft 49 (Fig. 6). he operating vconnection between shaft a5 49 and the carrier is provided byconnecting shaft of thev carrier with main shaft 49 by means of a spiral gear connection indicated at 52 (Figs.1 and 5). 5() is of constant drive, shaft 49 will be driven continuously but at reduced speed,

49, being also constantly driven. As a result, the' movements of the carrier will .be continuous while shaft is in operation.

Shaft 50'is driven from aA suitablel source of power (not shown), a suitable controlling friction clutch device connecting the power with the shaft. ln they drawings, 53indicates a pulley driven from the source of tion clutch, the complemental member being indicated at 53a, this member being moved Y toward and from pulley 53 by a suitable fork device 53 the movements ofy which are 55 Vunder the controlN of the operator by suitable treadle mechanism, not shown, the operating connections acting to provide movements to fork 53b so asto engage ordisengage the clutch device. lt will be obvious that the form of clutching mechanism disclosed is more or less illustrative, any suitable mechanism capable of being controlled bythe `operator being usable f or the purpose, it being understood j that'njthe operationcf this machine the face of the' lower charge,' the ad- 'the charge is actually grlpped.

As shown in Figs. .7l and Y8,) members 462- are ofJ considerable length and therefore provide a length of contact with the rear face of the charge extending over a considerable portion of said rear face, the' result 75 being that although @he charge is not gripped while being conveyed, its position v relative to members 46a will not be mate' `rially varied throughout the travel, these members 46@l having their directions of 80 length extending at direct right angles to the direction of travel of the carrier and advance the. charge without lateral shifting. Hence, the packet is not subjected to any grippingpressures vduring the advance of the charge, and at the same time, that portion of the wrapper which extends around the sidewalls of the packet is not subjected to damaging 'action such. as is liable where the lateral position of the charge onA the conveyer is determined by the magazine, such position being unchanged after the-charge has passed out of the posi- The initial folding action provided on the traveling charge is to turn-in the portions of the wrapper which are located at the ends of the narrower; side walls of the charge, asin Fig. 14,.'thus changing the conti uration and producing opposing flaps. hese turned-in portions maybe considered as end laps and are indicated at w. ln the drawl have showntwo -ways in which this, turning-in of the end laps may be provided, Fig. 31showing one way of producing this c and preferred way being disclosed in certain of the remaining figures.'

A preferred manner of producing vthis turning-in of the end laps is by the use of folding channels 54 having inwardly projecting ribs 54a 'spaced .from the top and bottom walls of the channel, the advance end of each rib being more or less curved in order to provide a nose operative to produce a gradual inturningof the end lap at the advancing end of the charge, the specific arrangement being shown more particularly in Figs. 17 to 19'inclusive.

As will be readily understood, the advancingI charge, in the form shown in Fig. 13, brings the advance end laps into contact with the nose of rib 54a, the continued advance ofthe charge causing these laps to be moved inward against the endwalls of the i wrapper thus l in lattempting'to 1- tabletop while the bers or ingers'57 Vfingers tending to retain the charge in position on thetable top while pass- 1n this stage.`

.\,Owing to the particular character of the wrapper, there may be a tendency of the unsupported ends of the 'latter to buckle atthe time when the end laps are being turnedem,

.this possibility being indicated by the full line position of the wrapper in F ig. 17. This buckling action is not detrimental fold is produced a result which is possible carry the end flap portions directl into the-small channels. To prevent l suc creasing or folding action, I preferably provide recesses 54 in the table top, and recesses 55a in plates 55 which form the upper walls of the folding channel, these-recesses permitting'the material of the end flaps to buckle outwardly, as shown in Fig. 17 soas to insure proper action ofthe' nose of ribs 54, it 'being readily understood that after. the lend lapshave been properly i' seated, the buckled llapswill resume the normal-position, the tendencyto .buckle being .present at the time when contact is first had with` the walls of the wrapper ends and during-the earlier stages of the'turning-in of the laps. ,J If desired, I may employ a spring linger v56, carried by themagazine for the purpose of holding the charge properly seated onthe charge is approaching the 'folding channel thus 'insurlng prov er registration of the c arge with the foldln channel.

As A the charge continues its advance, it is brought into the sphere of action of a pair of members which are adapted to fold or turn down the upper end ap to2, these members being stationary, the advancing movement of the charge causing the Hap to be turned down by the actionof folding faces carried-by these members.

The upper end iap folding members 64 are shown more particularly in Figs. 2, 4 and 2O to 24, being in the form .of blocks which are undercut to produce a channel or channels into and through which the unfolded end flaps pass. As shown more particularly in Figs. 21 to 24, the under cutting provides a narrow channel 64a adjacent the table top, this channel being of -uniform depth throughout the length of the member and is adapted to permit ofl the lfree passage of the lower end flap w3.' The portion of the undercut of member orblock 64 above ychannel 64a and indicated at 64", varies as to configuration, as shown in Figs. 21 to 24, this the advance endof the upper end flap to enter the member before turning-in action takes place (Fig. 21), after which such upper flap is progressively turned downward (Figs. 22 and 23) until it practically contacts with the end wall of the packet (Fig. 24), thus poviding the general in i the charge in folded condgigtion ready to receive the coating of adhesive whichis to be applied to the upper face of the lower endk flap by mechanism now to be described.

Detachably mounted on standards 65 posi-l tioned on opposite sides of the'travel path of the charge (Fig. 2) are adhesive containers 66, said containers each being adapted to carry a supply of adhesive which may be discharged through channels 66a formed at the bottoms of the containers (Fig. 9). Suitable means are provided for detachably conwith its standard, adjustment of each said parts also having an adjustable stop structure 67 adapted to limit the downward movement of the container. Each container has suitable mechanisms for controlling the flow of adhesive from thecontainer so as to` provide necting each container such means permittin container laterally (Fig. 8),

for the proper application anddistribution of the adhesive on to the face of -a roll 68 positioned above the top of table 40, said table having an opening- 40cbelow each roll 68. An independent roll 68 is provided on each side of the charge travel path,. said rolls being mounted on shafts 69 extending through bearings 69a, the rolls being prefer# ably adjustable in the direction of length of 15, and placingv the shaft, as shown more particularly in Fig. 9.

As shown in Fig. 2, rolls 68 are positioned at a point in direct succession to blocks 64, so that the advancing charge, in the form shown in Fig. 15, passes the upper face of flap w3 beneath a roll 68. Rolls 68 arejpositively driven, 7() meshing with a gear 71 mounted on shaft 72, said latter shaft having a direct connection with main shaft 49 through the spiral gear structure indicated at 7 3 (Fig. 5). As a result, the working faces of rolls 68 are constantly receiving a thin film of adhesive, the liaps w3 being passed into contact with this film as the charge advances, the direct drive connection between the main shaft and `the rolls insuring a proper timing action with respect to the speeds of travel of the charge and the rolls, so that the coating, as applied to the flaps w3, is uniformly distributed thereon, thereby practically insuring a neat appearance of the secured flap in the finished package.

T o more effectively .produce formityA in adhesive distribution, ably cause the flaps to be held-in contact with the adhesive-carrying face of the rolls by pressure applied on the under side ofthe flap. Since successive charges are spaced on vthe carrier, so that fiaps are presented to Yrolls 68 intermittently instead of continuously, the pressure-applying means must operate in an intermittent manner in order roll is not lthat the pressure-applying contact with the adhesive this uni- I prefereach shaft 69 carrying a gear carrying a roller 7 8a which is normally` adapted to ride of cam 77. In mechanism for applying adhesive in apparatus of this type, two general condi in contact with lthe periphery tions are presentl where it isdesired to provide a neat appearance to the package. One of these conditions is the uniform distribution of the adhesive on the flap-excessive pressure of the'fiap on the film will tend to affect such distribution. Hence, the pressure should be practically uniform, a result which can be obtained by vproviding a yielding connection between arm 75 and shaft 76. And since folding along the lines indicated herein practically provides end flapsvof unequal thickness, especially desirable. The other condition to be met is the possibilities resulting from this yielding connection is' usual manner.

` igs. 9 and 10, Fig. 9 showing` the pressure applications in a regular successiongwhere failure to present a charge at the proper time would bring the pressureapplying roller into direct contact with the adhesive coating of roll 68, a condition Where the adhesive would be transferred to the face of roll 74 andltend to `apply adhesive to the lower face of the succeeding end iap. These-conditions are met by providing -arms 75 with an elongated slot 75a into which the complemental key 7 5b carried by-shaft 76, extends, a vtension spring 79 being employed as the yielding connection between the arm andsha'ftfs'aid spring tending to maintain the arm with the key at one end ofthe slot, the slot permitting the arm to yield against the tension of spring 79 when pressure is being applied. vInmaddition, shafty 76 carries an arm 80 to `which one. end of a spring 81 is secured, the oppo-l site en d of I,the sprmg being connected to the frame of the machine (Fig. 2r), this spring also tending to move shaft 76 in the irection to applythe pressure. Excepting when pressure is to be applied, roller held out lof pressure-applying position (full line position of Fig. 25) through the action of the high part of camr 77 on, roller 78a which rocks shaft`76 in a direction to carry roller 74 out of its pressure-applying posi'- tion, arm 78 bein keyed to shaft 76 in the en, however, roller 78 passes on to the lower portion of cam 77, spring 8l will rock shaft76 to bring roller 4 into contact with the under'face of the thus bringing into -action the provided by spring 79. S mishap, the

ressure conould, by lany flap reach a. thickness greater .than the length lof slot 7 5.a, so that yielding to a suiiicient extent would not be permitted by such slot, spring 81 would form an addirelieve the excess pressure. As a result, the pressureapplicatin is automatically controllable so asto practically insure the proper uniform disof the adhesive on the flap.v

To meet the second condition indicated, I employ means, operated manually, for prethe position of the lever when it has been shifted so as to prevent such pressure-applying movements, lever.. 82 carrying a latch -device 83 coperating with a member 84 for retaining the lever in either extreme of its movement.l As shown in Figs. 9, 10 and 12, a lost motion action is provided between shaft 76 and lever 82` this lost motion device being shown as in the form of a slot 76a in shaft 76 and a pin 82a carried by the hub of lever 82 and which pin extends into slot 7 6a. vObviously any other type of lost motion connection may be employed. This lost motion device permits of the oscillation of shaft 76 under normal action without affecting the position of lever 82. When, however, the lever is shifted from the position shown in Fig. 9' to that shown'in full lines in Fig. 12, pin 82a asses to a position where it prevents oscil ation of shaft 76 and thus retains roller 74 in an inoperative position.` By means of the latching mechanism, it will be readily understood that shifting of the lever to retain roller 74 in inoperative position can be had with rapid ity, and the roller be maintained in such position until the lever is again returned to itsnormal position. This is of advantage to meet emergencies.

The advancing charge, with its adhesivelycoated lower end fia-ps then enters the zone of activity of folding devices adapted to turn-up these lower end laps into overlapping 'relation to and into adhesive connection with the previously turned-in laps and flaps, the members for producing this action being shown more particularly in Figs. 20,

land 26 to 30 inclusive, these members being .the successive venting arm 78"fr`om moving in pressureapplying direction, thus retaining roller 74 out of with the adhesive roll 68 in would contact case the charge is not present at the time of ,Ipressure-applying movement of arm 75.

1 As shown in Fig. 20, blocks 64 and 85 are spaced apart and are successively operative on the charge as the ylatter advances, rolls 68 being made operativ/e on the charge between operations of block 64 and 85. n understood, the upper end flap is held in its down-turned-position-by block 64 as long as the charge is within the eifective zone of said block.` Since, however, application of adhesive and the turning-up of the lower end flap by means of a stationary block structure, requires exposure of the ad. hesive-receiving face and a free movement of the end Hap during the turning-up action, block 85, cannot,- itself, retain the turned-in upper end flap. Hence, I have provided a member 86 which, if desired,l maybe supported by blocks 64 and 85, this member carrying a downwardly `extending blade 86a (Figs. 4 and 20), this blade being positioned to retain the turned-down upper fiap in its folded position, as shown `for instance in Figs. 26 to 28, the result being that the pre- 130 .Als will be blocks havingA the horizontal and ,verticale viously properly held in position during the time when the-lower flap is receiving its adhesive coating and while it is being turned upward by block 85, the blade having its lower edge leading outof the plane of travel of the charge prior to the time when the vertical wall of the cut-away portion of block 85 brings the flap being turned into contact with the folded flapv and laps. The fact that the active portion of the blade terminates prior to complete turning-up of the flap, does not materially aect the operation Afor the reason that the activity of the blade continues until the rear of the charge practically passes out of contact therewith, at which time blocks 85 have practically completed the vfoldin at the advance end ofthe charge, causing the adhesive connection to retain the folds.

As will be seen by an-inspection of Figs. 21 to 24 and 26 to 30, each of blocks 64 and 85 have faces which are active in flap turntaking place ing operations, the flap-turning t e carrier, the

as the charge is advanced by faces joined by curved'face portions at an intermediate point so that the outer edges of l the flaps will be readilyguided inthe proper direction without damage eventhoughthe material is relatively thin.

' As shown in Fig.

3(1), closing ofthe ends of the charge is completed when the travel of the charge carries 1t from the zone of memsfber 85, thus producing the Vpackage illus-f trated in Fig. 16.

As shown in this view?, the

As will be Aunderstood the lcompleted from manner. In'the drawings, however, I have shown the use of a receivmg table or structure 88 into which vthe cessively rpackages are sucdelivered as shown more particularly in 46a will continue to advance the package until it is `lcarried out ofcontact with the rearv face of 4thepaekage by its movement in rounding shaft 45, thus'leaving the package resting on the table top. As

the succeeding package is delivered, its adi Vance face contacts with the rear face of the previously vdelivered package, so that the latter then advances and passes o n to the table 88, being preferably held in an inclined position by face 88 of the table, the advance of the succeeding package advancing the packages previously on the table'and itself becomlng the rearmost` package on such table, the result being that the packages are practically collectedA on the table from which they may be removed in quantities in anA obvious manner.

From the above description it will be seen Athat the charge is continuously in movement from the time it leaves the magazine untilY it passes out ofcontact with its advancing member' 46a, movement, the successive operations thereon taking place while the charge is moving, these operations being provided by stationary device's with the exception of the turning-in of the rear end laps and the application of the adhesive, all of these operations Vtaking place while the charge is traveling in substantially a "single horizon-l tal plane.v Furthermore, those operations which require moving parts are all driven from the same shaft- 49-withithe operundergoing its 'end lap turning-1n, vso that, instance shown, two

This enables the use ofV the endless conveyer type of carrier with theconveyer pro-`VV vided with a number` of members 46a which successively remove charges from themagazine and deliver the completed packages on. vto table 88, the only requirement practically being to keep the withi a fsuiicient number .of
